`CH_(3)Br+Nu^(-)rarrCH_(3)Nu+Br^(-)`
The decreasing order of the rate of the above reaction with nucleophiles `(Nu^(-))` A to D is :
`[Nu^(-)=(A)PhO^(-),(B)AcO^(-),(C)HO^(-),(D)CH_(3)O^(-)]`

A

`D gt C gt A gt B`

B

`D gt C gt B gt A`

C

`A gt B gt C gt D`

D

`B gt D gt CgtA`

Text Solution

Verified by Experts

The correct Answer is:
A
Since this reaction will follow `S_(N^2)` pathway so stronger the base better its nucleophilicity. The correct order of nucleophilicity would be
`CH_3O^(-) gt OH^(-) gt phO^(-) gt AcO^(-)`
